Data Governance
This final stage involves setting policies, procedures, and standards to manage data quality over time. Data governance ensures that data quality practices are sustainable and comply with regulatory requirements, and that roles and responsibilities are clearly defined across the organization.
Data Monitoring and Maintenance
Once data has gone through cleansing and validation, it needs to be continuously monitored and maintained to ensure its quality over time. Regular audits and updates are essential to identify and address any emerging issues, ensuring that the data remains reliable and up-to-date.
Data Collection
This is the first stage, where data is gathered from various sources. It's crucial to ensure that the data being collected is relevant and comes from trustworthy and consistent sources.

Data Validation
At this stage, the data is checked against predefined rules or standards to ensure it meets certain quality criteria. Validation can include checking for correct data types, valid ranges, and ensuring that the data adheres to business rules or logic.
Data Profiling
In this stage, data is analyzed to understand its structure, quality, and content. Profiling helps to identify issues such as duplicates, inconsistencies, or missing values, providing a foundation for the next steps.
Data Cleansing
At this stage, we define data quality rules that are used to cleanse and improve the quality of your data. This stage involves identifying and correcting errors or inconsistencies within the data. It includes removing duplicates, filling in missing values, standardizing formats, and correcting inaccuracies to improve the overall quality of the data.
